Abstract

The invention relates to a network capable of switching a terminal from 3GPP to a wireless local area network (WLAN). The network comprises a 3GPP access network, a WLAN access network and a 3GPP core network, wherein a home location register, a service node, a gateway service node and a terminal management server is also arranged in the 3GPP core network; and a WLAN access gateway is arranged between the WLAN access network and the 3GPP core network. The network has the advantages of realizing seamless switching of services without mobile IP technology, supporting superposed mobile IP technology application, meeting the requirement of EPC network evolution in the future, not changing original equipment of the conventional core network, quickly pushing WLAN and 3GPP fused services, promoting the development of fixed mobile convergence (FMC) services, along with low network design and realization cost and simple realization of terminal equipment.

Description

【Technical field】 [0001] The invention relates to the field of communication technology, in particular to a network and a switching method capable of switching terminals between 3GPP and WLAN. [0002] In this field, the standard specification definitions of 3GPP2 and RFC are all in English. In order to make the narration of this patent adapt to the standard specification definition, the description of message interaction in this patent narration and the accompanying drawings all refer to the corresponding 3GPP2 and RFC The English narration in the standard specification definition of , and the Chinese description is given at the appropriate position. [0003] The terminal uses SIP signaling to complete the access process to the WLAN network, and may also use signaling formats defined by other international standard organizations. 【Background technique】 [0004] The series of specifications since 3GPP R7, such as 3GPP TS 23.234V7.6.0, describe the I-WLAN (Interworking WLAN)...
